It's a 10 handed game I just joined. Sorry for the lay out, I'm typing on my phone. First hand posting in many years. All tips are welcome.

Preflop $4 straddle I'm on the cutoff.

Straddle $290
BB $500
Hero $330 8 9
Limpers about $120 to $150

Preflop

2 Limpers
hero raise $14 I wanted to play in position against 1 or 2 of the limpers.
Bb reraise $42
Straddle Call $42
Limper 1, 2 call $42
Hero call $42 Shoving calling and folding all seemed reasonable, but then I thought I would have no fold equity and being in position made me call

Flop

A 8 3

Bb bet $60
straddle all in
Limp 1,2 fold
Hero all in
Bb fold

You are only 82.5 bb’s deep here. You’re far better off simply limping behind pre instead of trying to iso raise (only 3.5x) small, which will never fold anybody out and will only bloat the pot or leave you vulnerable to squeeze plays (as happened here).
After that, I don’t know. Call and fold to the $42 are both bad options. Fold is probably slightly better. You almost flopped as good as you can here and you might be drawing dead to trip 8’s or two pair.
Summary: you put yourself in an awkward spot pre.

Limp pre
Fold to the 3b

Flop: Do whatever you want as long it doesn't involve folding

Playing suited connectors in a low-SPR pot sounds like a money-loser to me.

Your initial raise is too small. If you want to play head-up in position, you have to give the droolers a reason to fold. Iso to something like $30 here. Against two limpers already, 3.5x is just a weak-ass potbuilder raise, and bad players treat these like catnip.

And yeah, with a stack of 330, in a straddle pot you've only got 83bb, so you should be de-emphasizing implied-odds hands and going more for big cards.

So I wouldn't iso with this hand; I would iso for about twice as much; and as played when the action comes back to me with a 3-bet, I am inclined to ignore the price the pot appears to be laying and just fold.

As played, with the ace of trump on the board, that cuts significantly into the number of flush-draw combos other villains can have. Put the money in, and when you do, remember that if you lose here, it is because you put yourself into this spot by your preflop play.

Thanks for the answers. They are very helpful. I never really thought about the straddle as a big blind, but now it is obvious.

What range would you bet (is it raise or bet after straddle?) preflop in my spot and no useful reads/history?

Technically the small blind and big blind are bets so if you make it more you are raising from the get go. The same is true for the straddle. But people call the first raise a bet because they don't think of the other ones before hands are dealt as real bets.

As for what sort of range to raise with, with short effective stacks, unknown opponents and a couple of limps already go with a pure strong value range. Something like AQ+, TT+. With effective stacks that short even if your $14 get you heads up you would be committed with any pair. You can open that up a bit after you have better reads.

{AQ+, TT+} is far too nitty. As the effective stacks go down, one can find opportunities in weaker aces, hands as weak as KTo, and so on. The raw equity of big cards becomes more important, because as SPR goes down the ability of big cards to realize their equity goes up.
